IM PROVED EVA PO RATO R.

Specification forming part ofLetters Patent No. 58,607, dated October 9,1866.

To all whom it may concern:

Be it known that I, J. COOPER, of Mount Vernon, in the county of Knoxand State of Ohio, have invented a new and Improved Evaporator; and I dohereby declare that the following is aful l, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference bein g had to the accompanying drawings,forming part of this specification, in which- Figure 1 represents alongitudinal vertical section of this invention, the lines aa, Fig. 2,indicating the plane of section. Fig. 2 is a plan or top View of thesame. Fig. 3 is a transverse vertical section of the same, taken in theplane indicated by the line y 3 Fig. 2. Fig. 4. is a vertical section ofone of the partitions, in alarger scale than the previous figures, theline 2 2, Fig. 2, indicating the plane of section. Fig. 5 is a similarsection through the gate in one of said partitions, the plane of sectionbeing indicated by the linez 2, Fig. 2. Fig. 6 is a horizontal sectionof the same.

Similar letters of reference indicate correspondin g parts.

This invention relates to a pan for evaporatin g saccharine and otherliquids which is provided with a sheet-metal bottom, and with pantitions of gradually-increasing height, which are produced either bydoubling the bottom up, or, if desired, the bottom can be in severalsections, the ends of which are turned up and bent one over the other,and over suitable wires used for strengthening the top edges of thepartitions. Each of the partitions is provided with one or more gates,which fit into guide-strips attached to the edges of the gateopenings,and these guide-strips are formed by turning over the edges of pieces ofsheet metal, which are fastened to the partition by cars catching overthe edges of the gate-openings.

A represents a pan intended for evaporating saccharine or other liquids.The sides B of this pan are made of wood, or any other suitablematerial, and to these sides the bot tom 0 is fastened by nails orbrackets, or by any other suitable means. Said bottom is made of sheetmetal, copper or galvanized iron be ing used by preference, and it is soarranged that the depth of the pan increases gradually, as clearly seenin Fi 1.

A series of transverse partitions, D, divide the pan in four (more orless) compartments and close in front of each partition. A well ordepression, a, is formed in the bottom, whereby the effect of the heaton the pan is better and more economical than it is when the bottom ofthe pan is smooth and even throughout its entire length. The partitionsare formed either by doubling up the bottom, if the same is made of onecontinuous sheet of metal, or, if the bottom is made in severalsections, as will be generally the casein practice, the ends of eachsection are turned up and secured together by turning one end over theother, and, if desired, the top edges of the partition can bestrengthened by wires, which are held in position by the edge of onesection being turned over the same and over the edge of the othersection, as shown in the drawings. Each partition is furnished with oneor more gates, E, which move in suitable guide-strips V. Theseguide-strips are formed by turning up the edges of suitable metalplates, which are fastened in the gate-openings d by means of ears 0,turned over the edge of said openings, as shown particularly in Fig. 5of the drawings, By these ears the parts of the partitions in theneighborhood of the gate-openings are strengthened and made tight, andthe guidestrips are firmly retained, so that they are not liable tobreak off or get deranged.

An evaporator can thus be constructed at a comparatively small expenseand of superior durability and great economy in working the same.

What I claim as new, and desire to secure by Letters Patent, is-

The ears 0, in combination with the guidestrips V, gate-openings d, andpartitions D, constructed and operating substantially as and for thepurpose described.
